Create a ZIA Cloud Firewall Filtering rule that controls network traffic by source/destination IP, country, network application, network service, device trust level, user/group/department, location, and optional time-of-day schedule (Time Interval). Supported actions: ALLOW, BLOCK\_DROP, BLOCK\_RESET, BLOCK\_ICMP, EVAL\_NWAPP. Use when an admin asks to 'create a firewall rule', 'block traffic to X', 'allow traffic from Y', 'block country Z', 'restrict access during business hours', or 'add a firewall exception'. This skill creates exactly one Cloud Firewall rule and chains to \`zia-manage-time-interval\` when the admin's request includes a recurring schedule.

## From README

ZIA: Create Cloud Firewall Filtering Rule How to talk to the admin Don't narrate tool calls, search filters, or internal lookup logic. Just confirm what was created and which scoping was applied. Empty list responses are authoritative. If a zialist lookup returns no match for an exact-name search, treat the resource as "does not exist." Do not retry with split keywords or unfiltered listings. Don't claim a tool doesn't exist without checking. If ziacreate and ziaget are visible for a resource, the matching zialist exists too. Don't narrate strategy pivots. If you have to retry quietly, retry quietly and report only the final outcome. After every successful create, mention the activation step explicitly — ZIA changes are staged until activated. The agent must call ziaactivateconfiguration() and tell the admin the change is now live. Scope of this skill This skill creates one Cloud Firewall Filtering rule per invocation.
